Abstract
According to one embodiment, an inductor device includes a first pad and a second pad. The first pad includes a first compensation part located in a first direction side and a first inductor part located in a second direction side. The second direction is an opposite direction of the first direction. The second pad includes a second compensation part located in the second direction side and a second inductor part located in the first direction side. The first compensation part and the second compensation part each include a compensation capacitor. The first inductor part includes a first core and a first coil winded around the first core. The second inductor part includes a second core and a second coil winded around the second core.

An inductor device comprising:
- a first pad including a first compensation capacitor located in a first direction side and a first core and a first coil winded around the first core located in a second direction side, the second direction being an opposite direction of the first direction, the first compensation capacitor being coupled with the first coil, and the first coil being configured to perform one of:
- generating a magnetic field based on a first current flowing through the first coil and coupling the magnetic field with a first target coil of a target inductor device to transmit an electric power, the first current having a first phase, or
- coupling with a first target coil of a target inductor device via a magnetic field from the first target coil to generate a first current depending on the magnetic field through the first coil to receive an electric power, the first current having a first phase;
- and
- a second pad including a second compensation capacitor located in the second direction side and including a second core and a second coil winded around the second core located in the first direction side, the second compensation capacitor being coupled with the second coil, and the second coil being configured to perform one of:
- generating a magnetic field based on a second current flowing through the second coil and coupling the magnetic field with a second target coil of the target inductor device to transmit an electric power, the second phase being an inverse phase of the first phase, or
- coupling with a second target coil of the target inductor device via a magnetic field from the second target coil to generate a second current depending on the magnetic field through the second coil to receive an electric power, the second phase being an inverse phase of the first phase.
